Proficiency based tutorial modification

ABSTRACT

In implementations of proficiency based tutorial modification, a computing device implements a tutorial system to receive a user modification of a digital image. A difference between the user modification and an application modification of the digital image is determined. The tutorial system generates a proficiency score for an editing tool based on the difference between the user modification and the application modification, and the proficiency score indicates the user&#39;s proficiency in using the editing tool. The tutorial system generates a pre-modified input image for a tutorial depicting a modification applied to an input image to be modified in the tutorial using the editing tool based on the proficiency score for the editing tool being greater than a proficiency threshold.

RELATED APPLICATIONS

This application is a continuation of and claims priority to U.S. patent application Ser. No. 16/813,441, filed Mar. 9, 2020, entitled “Proficiency Based Tutorial Modification,” the entire disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

Applications for creating and/or editing digital content often include large sets of editing tools which can be used to adjust features of the digital content. For example, an application for editing digital photographs may include editing tools usable to adjust visual features of the digital photographs such as an exposure, a contrast, a color temperature, etc. Since many of these editing tools are complicated to use, applications frequently include tutorials which describe how to use the tools to adjust the features of the digital content. Thus, it is common for users of the applications to view these in-application tutorials or other tutorials to learn to become proficient using various digital content editing tools.

Conventional systems commonly generate tutorials as including information that is already known to many potential viewers of the tutorials. As a result, tutorials generated using conventional techniques typically include some tutorial steps which are informative to a particular user as well as other tutorial steps describing editing tools which the particular user has already mastered. Displaying these other tutorial steps to the particular user is an inefficient use of computational and/or network resources as well as a source of frustration to the particular user.

SUMMARY

Systems and techniques are described for proficiency based tutorial modification. In an example, a computing device implements a tutorial system to receive a user modification of a digital image. This user modification corresponds to a user's use of an editing tool of editing tools of an application to edit the digital image. The editing tools of the application correspond to tutorial steps of a tutorial. For example, the tutorial may be for editing an input image using the editing tools corresponding to the tutorial steps. The tutorial system determines a proficiency score for the editing tool used to edit the digital image. This proficiency score indicates the user's proficiency in using the editing tool, and the tutorial system can determine proficiency scores in several ways.

In one example, the tutorial system determines a difference between the user modification and an application modification of the digital image which corresponds to use of an algorithm of the application to edit the digital image. The tutorial system may calculate the proficiency score for the editing tool based on the difference between the user modification and the application modification. This proficiency score is then compared to a proficiency threshold. In one example, the tutorial system determines that the proficiency score for the editing tool is greater than the proficiency threshold which indicates that the user is proficient in using the editing tool.

Based on this determination, the tutorial system generates a modified tutorial by removing a tutorial step corresponding to the editing tool from the tutorial steps of the tutorial. In this way, the modified tutorial does not include the tutorial step describing how to use the editing tool that the user is already proficient using. In one example, the tutorial system generates a pre-modified input image for the tutorial. In this example, the pre-modified input image depicts a modification applied to the input image using the editing tool. Thus, pre-modified input image can be further modified using editing tools corresponding to tutorial steps of the modified tutorial.

This Summary introduces a selection of concepts in a simplified form that are further described below in the Detailed Description. As such, this Summary is not intended to identify essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

DETAILED DESCRIPTION

Overview

Tutorials generated and displayed using conventional systems include tutorial steps describing how to use editing tools of applications for creating and/or editing digital content. These tutorials describe the editing tools at levels of detail which can be understood by the most novice of users viewing the tutorials. This is because conventional systems have no information about the users viewing the tutorials. As such, tutorials generated using conventional techniques frequently include tutorial steps describing use of a multitude of editing tools which are already well understood by many of the users that are viewing the tutorials to learn how to use a specific editing tool. Since conventional tutorials are invariable in nature, these users may be forced to view several uninformative tutorial steps in order to view the tutorial step describing the specific editing tool. Displaying uninformative tutorial steps in this way is an inefficient use of computational resources and also frustrating to users.

Systems and techniques are described for proficiency based tutorial modification. In one example, a computing device implements a tutorial system to receive input data which includes a user modification of a digital image. The user modification corresponds to a user's use of an editing tool of editing tools of an application to edit the digital image. These editing tools are associated with tutorial steps of a tutorial that describe how to use the editing tools to create and/or edit an input image.

The tutorial system processes the input data to identify the editing tools used by the user and then generates a proficiency score for each of the identified editing tools. These proficiency scores indicate the user's proficiency in using the identified editing tools as part of creating and/or editing digital images. In an example, the tutorial system determines a difference between the user modification and an application modification of the digital image. The application modification corresponds to use of an algorithm of the application to edit the digital image. In this example, the tutorial system may compute a proficiency score for the editing tool based on the difference between the user modification and the application modification. This proficiency score is then compared to a proficiency threshold. For example, the tutorial system determines that the proficiency score for the editing tool is greater than the proficiency threshold which indicates that the user is proficient in using the editing tool.

Based on this determination, the tutorial system generates a modified tutorial by removing a tutorial step corresponding to the editing tool from the tutorial steps of the tutorial. Accordingly, the modified tutorial does not include the tutorial step describing how to use the editing tool that the user is already proficient using. In an example, the tutorial system generates a pre-modified input image for the tutorial. In this example, the pre-modified input image depicts a modification applied to the input image using the editing tool. In this way, pre-modified input image may be further modified using editing tools corresponding to tutorial steps of the modified tutorial.

The tutorial system can also leverage the proficiency scores in other ways such as to reorder tutorial steps in the modified tutorial. In one example, the tutorial system may arrange tutorial steps of the modified tutorial in ascending order of proficiency scores for editing tools described by the tutorial steps. In this example, a tutorial step associated with an editing tool having a lowest proficiency score is presented first and a tutorial step associated with an editing tool having a highest proficiency score is presented last. In this way, the user viewing the modified tutorial learns how to use editing tools described by the tutorial steps starting with editing tools for which the user is least proficient which can increase user engagement as the user is learning something new. This functionality can be alternative or in addition to removing tutorial steps from the modified tutorial which describe editing tools that the user is already proficient using.

The tutorial system can also calculate chapter proficiency scores for tutorials organized into chapters such that each chapter includes multiple tutorial steps. In an example, the system calculates the chapter proficiency scores as an average score of the proficiency scores of the tutorial steps included in the chapters. In this manner, the tutorial system can order chapters in ascending order of chapter proficiency scores associated with the chapters. This can further improve user engagement and retention as the user learns chapters of the modified tutorial starting with the chapters having tutorial steps describing editing tools for which the user is least proficient.

The described systems and techniques improve conventional tutorial generation technology that generates tutorials which describe how to use editing tools without having any information about the proficiency of users in using the editing tools. By generating modified tutorials without tutorial steps describing editing tools for which a user is already proficient using, the described systems conserve computational resources used to display uninformative tutorial steps. The described systems and techniques also improve computer-based tutorial generation technology by modifying tutorials to customize an order of presentation of tutorial steps based on proficiency of the user in using editing tools described by the tutorial steps. In this way, the user can learn to use the least familiar editing tools first which increases user engagement and retention.

Term Descriptions

As used herein, the term “editing tool” refers to an element of an application for creating and/or editing digital content usable to implement editing functionality for the digital content. By way of example, a user can use an editing tool to apply a user modification to the digital content. By way of further example, a user can use a white balance editing tool to apply a white balance modification to the digital content.

As used herein, the term “algorithm” refers to an element of an application for creating and/or editing digital content usable to implement functionality of at least one editing tool to edit digital content according to a defined protocol. The defined protocol may be learned using machine learning, where a machine learning model is trained using training images to adjust values of images to produce visually pleasing images. By way of example, an application for creating and/or editing digital content can use an algorithm to apply a modification to the digital content which may be in response to a user input. By way of further example, an application for creating and/or editing digital content can use a white balance algorithm to apply a white balance modification to the digital content which can be in response to a user input.

In the following discussion, an example environment is first described that may employ the techniques described herein. Example procedures are also described which may be performed in the example environment as well as other environments. Consequently, performance of the example procedures is not limited to the example environment and the example environment is not limited to performance of the example procedures.

Example Environment

FIG. 1 is an illustration of an environment 100 in an example implementation that is operable to employ digital systems and techniques as described herein. The illustrated environment 100 includes a computing device 102 connected to a network 104. The computing device 102 may be configured as a desktop computer, a laptop computer, a mobile device (e.g., assuming a handheld configuration such as a tablet or mobile phone), and so forth. Thus, the computing device 102 may range from a full resource device with substantial memory and processor resources (e.g., personal computers, game consoles) to a low-resource device with limited memory and/or processing resources (e.g., mobile devices). Additionally, the computing device 102 may be representative of a plurality of different devices, such as multiple servers utilized by a business to perform operations “over the cloud.”

The illustrated environment 100 also includes a display device 106 that is communicatively coupled to the computing device 102 via a wired or a wireless connection. A variety of device configurations may be used to implement the computing device 102 and/or the display device 106. The computing device 102 includes a storage device 108 and a tutorial module 110. The storage device 108 is illustrated to include digital content 112. An example of the digital content 112 is a digital image 114 which is displayed in a user interface 116 of the display device 106.

The tutorial module 110 is illustrated as having, receiving, and/or transmitting user data 118 and tutorial data 120. The tutorial data 120 describes various tutorials which can be rendered to describe features and tools of applications for creating and/or editing the digital content 112. For example, the computing device 102 can implement the tutorial module 110 to process the tutorial data 120 to generate a tutorial 122. As illustrated, a representation of the tutorial 122 is rendered in the user interface 116 of the display device 106.

In this example, the tutorial 122 includes tutorial steps 124-134 which correspond to instructions for using editing tools to edit the digital image 114, e.g., using an application for creating and/or editing the digital content 112. By way of example, tutorial step 124 may describe use of an exposure editing tool which can be used to adjust an overall brightness depicted in the digital image 114. In another example, tutorial step 124 can describe use of a contrast editing tool which can be used to increase or decrease a contrast depicted in the digital image 114. Thus, tutorial steps 124-134 can each describe use of any tool for editing and/or creating the digital image 114.

The user data 118 describes a user's use of editing tools as part of creating and/or editing the digital content 112. For example, the user data 118 can include digital images which the user has created and/or edited using editing tools of an application for creating and/or editing the digital content 112. The user data 118 is illustrated to include a representation 136 of tutorial steps of the tutorial 122 which describe use of editing tools for which the user is already proficient. For example, the computing device 102 implements the tutorial module 110 to process the user data 118 to determine particular editing tools which the user has used to edit the digital content 112.

After determining the particular editing tools which the user has used, the tutorial module 110 further processes the user data 118 to determine whether the user's use of the particular editing tools indicates that the user is proficient in using the particular editing tools. To do so, the tutorial module 110 generates a proficiency score for each of the particular editing tools. The tutorial module 110 can generate these proficiency scores in several ways. In one example, the tutorial module 110 generates a proficiency score for a particular editing tool based on a number of times the user has used the particular editing tool to create and/or edit the digital content 112. In this example, the tutorial module 110 compares the number of times that the user has used the particular editing tool to a use threshold as part of computing a proficiency score for the particular editing tool. In one example, the tutorial module 110 can compute a proficiency score based on a determination that a number of uses of the particular editing tool is greater than a use threshold.

In another example, the tutorial module 110 generates a proficiency score for the particular editing tool based on a number of times the user has used the particular editing tool as well as a number of times that the user has correctly used the particular editing tool. In this example, the tutorial module 110 can determine whether a use of the particular editing tool is a correct use of the particular editing tool by comparing features of the user's use of the editing tool to features of a known correct use of the particular editing tool. For example, a user value applied to the digital content 112 by the user using the particular editing tool may be compared to an application value computed using an algorithm of the application for creating and/or editing the digital content 112 to approximate a correctness of the user's use of the particular editing tool.

Consider an example in which the tutorial module 110 generates a proficiency score for a white balance editing tool by determining a user white balance modification applied by the user to a digital image of the digital content 112 using the white balance editing tool. The tutorial module 110 then determines a white balance modification applied to the digital image of the digital content 112 by a white balance algorithm of an application for creating and/or editing the digital content 112. In this example, the tutorial module 110 may calculate a difference between the user white balance modification applied by the user and the white balance modification applied by the white balance algorithm. The tutorial module 110 compares this difference to a threshold and if the difference is less than the threshold, then the tutorial module 110 determines that the user's use of the white balance editing tool is approximately correct. Alternatively, if the difference is greater than the threshold, then the tutorial module 110 determines that the user's use of the white balance editing tool is not correct.

Continuing the previous example, the tutorial module 110 compares white balance modifications applied to additional digital images by the user using the white balance editing tool with white balance modifications applied to the additional digital images by the white balance algorithm. For each instance of the user's use of the white balance editing tool, the tutorial module 110 can approximate a correctness of the user's use of the editing tool by comparing the user's applied white balance modifications to white balance modifications applied by the white balance algorithm In this way, the tutorial module 110 can determine a total number of times the user used the white balance editing tool correctly which the tutorial module 110 can leverage to generate a proficiency score for the white balance editing tool.

For example, the tutorial module may determine the user's proficiency in using the white balance editing tool based on the number of times the user correctly used the white balance editing tool. The computing device 102 implements the tutorial module 110 to generate a proficiency score for the white balance editing tool based on the number of times the user correctly used the white balance editing tool. In this example, the tutorial module 110 can compare the proficiency score for the white balance editing tool with a proficiency threshold. If the proficiency score for the white balance editing tool is greater than the proficiency threshold, then the tutorial module 110 can determine that the user is proficient in use of the white balance editing tool. Alternatively, if the proficiency score for the white balance editing tool is less than the proficiency threshold, then the tutorial module 110 may determine that the user is not proficient in use of the white balance editing tool.

Additional techniques for approximating a correctness of the user's use of an editing tool and/or generating proficiency scores for the user's use of editing tools are contemplated. Consider another example in which the tutorial module 110 generates a proficiency score for the user's use of a lighting effect editing tool by determining a lighting effect value applied to the digital image of the digital content 112 by the user using the lighting effect editing tool. The tutorial module 110 then determines a lighting effect value applied to the digital image of the digital content 112 by a machine learning model, e.g., a convolutional neural network, trained using training data to learn to correctly use the lighting effect editing tool. In this example, the tutorial module 110 calculates a difference between the lighting effect value applied to the digital image of the digital content 112 by the user and the lighting effect value applied to the digital image by the machine learning model. The tutorial module 110 then compares this calculated difference to a threshold. If the calculated difference is less than the threshold, then the tutorial module 110 determines that the user's use of the lighting effect editing tool is approximately correct. Alternatively, if the calculated difference is greater than the threshold, then the tutorial module 110 determines that the user's use of the lighting effect editing tool is not correct.

In the previous example, the tutorial module 110 can approximate a correctness of a user's user of a particular editing tool using a machine learning model, e.g., a convolutional neural network, trained to identify a correct use of the particular editing tool. In another example, the tutorial module 110 approximates a correctness of a user's use of a particular editing tool using a machine learning model trained to identify an incorrect use of the particular editing tool. In these examples, the tutorial module 110 determines that a particular editing tool has been used to edit a digital image of the digital content 112. The tutorial module 110 then uses the trained machine learning model to generate an indication of a correctness of the use of the particular editing tool, e.g., by processing the digital image of the digital content 112. In this way, the tutorial module 110 can determine a total number of times the particular editing tool is correctly used to edit digital images of the digital content 112 and the tutorial module 110 may then generate a proficiency score for a user's use of the particular editing tool based on the total number of correct uses of the particular editing tool.

In the illustrated example, representation 136 includes tutorial steps 124, 126, and 132 which correspond to a first editing tool, a second editing tool, and a third editing tool, respectively, for which the user is already proficient. The tutorial module 110 processes tutorial data 120 and the user data 118 which includes the representation 136 to generate a modified tutorial 138. A representation of the modified tutorial 138 is rendered in the user interface 116 of the display device 106.

As shown, the modified tutorial 138 includes tutorial steps 128, 130, and 134 and the modified tutorial 138 excludes tutorial steps 124, 126, and 132. Thus, the tutorial module 110 generates the modified tutorial 138 as excluding tutorial steps which correspond to editing tools that the user is determined to be proficient using. In this way, the modified tutorial 138 represents a customized version of the tutorial 122 which excludes tutorial steps that describe editing tools based on the user's proficiency with the editing tools.

The computing device 102 also implements the tutorial module 110 to generate a modified digital image 140 which is displayed in the user interface 116 of the display device 106. This modified digital image 140 is the digital image 114 with editing applied using the editing tools corresponding to the excluded tutorial steps 124, 126, and 132. Thus, the modified digital image 140 is a pre-modified digital image depicting modifications applied to the digital image 114 using the editing tools corresponding to the excluded tutorial steps 124, 126, and 132. In one example, visual features applied to the digital image 114 using editing tools described in the tutorial steps 124-134 may be order independent such that the digital image 114 modified by editing tools described by tutorial steps 124-134 will be the same as the modified digital image 140 modified by editing tools described by tutorial steps 128, 130, and 134.

FIG. 2 depicts a system 200 in an example implementation showing operation of a tutorial module 110. The tutorial module 110 is illustrated to include a proficiency module 202, a comparison module 204, and a modification module 206. The proficiency module 202 receives the user data 118 and processes the user data 118 to generate proficiency score data 208. For example, the proficiency module 202 processes the user data 118 and identifies uses of editing tools as part of creating and/or editing digital images included within the digital content 112.

The proficiency module 202 then determines a minimum number of times the identified editing tools should be used to become eligible for determining a proficiency of the user's use of the identified editing tools. This minimum number of uses may be specific to individual editing tools of the identified editing tools. For example, a relatively difficult or complicated editing tool may have a greater minimum number of uses for eligibility than a relatively easy or simple editing tool.

The proficiency module 202 processes the user data 118 and determines a number of times the user has used each of the identified editing tools. In one example, the proficiency module 202 can determine the number of uses of a particular editing tool on a per digital image basis. In this example, if the particular editing tool is used multiple times to modify a particular digital image of the digital content 112, then the proficiency module 202 considers this use as a single use of the particular editing tool. For example, if the proficiency module 202 determines that the particular editing tool was used three times to edit one particular digital image, then the proficiency module 202 determines that particular editing tool is used one time based on the one particular digital image.

In another example, the proficiency module 202 determines the number of uses of a particular editing tool on a per use basis. In this example, if the proficiency module 202 determines that the particular editing tool was used three times to edit one particular image, then the proficiency module 202 determines that the particular editing tool is used three times. In an additional example, the proficiency module 202 can determine a number of uses of the particular editing tool on a per digital image basis and on a per use basis. In this way, the proficiency module 202 can distinguish between limited use of a particular editing tool to edit multiple digital images of the digital content 112 and extensive use of the particular editing tool to edit a single digital image.

The proficiency module 202 can generate a proficiency score for each identified editing tool based on the minimum number of uses for proficiency determination eligibility and the determined number of uses of each identified editing tool. The proficiency module 202 generates the proficiency score data 208 describing the generated proficiency score for each identified editing tool. In an example, the proficiency module 202 also determines a number of correct uses for each identified editing tool. In this example, the proficiency module 202 generates a proficiency score for each identified editing tool based on the minimum number of uses for proficiency determination eligibility, the determined number of uses, and the determined number of correct uses of each identified editing tool. The proficiency module 202 then generates the proficiency score data 208 as including data describing the proficiency score generated for each identified editing tool.

The comparison module 204 receives the proficiency score data 208 and the comparison module 204 processes the proficiency score data 208 to generate proficiency data 210. For example, the comparison module 204 can include a threshold module 212 and the comparison module 204 can implement the threshold module 212 to process the proficiency score data 208 to determine the user's proficiency in using the identified editing tools. To do so, the threshold module 212 compares each proficiency score described by the proficiency score data 208 to a proficiency threshold. The comparison module 204 then generates the proficiency data 210 describing indications of results of these comparisons.

For example, each proficiency score included in the proficiency score data 208 can correspond to one of the tutorial steps 124-134. Thus, each of the identified editing tools corresponds to one of the tutorial steps 124-134 in this example. By comparing each proficiency score of the identified editing tools to a proficiency threshold associated with the identified editing tools, the threshold module 212 determines that the user is proficient using a particular editing tool if the proficiency score for the particular editing tool is greater than the proficiency threshold for the particular editing tool. If the proficiency score for the particular editing tool is less than the proficiency threshold for the particular editing tool, then the threshold module 212 determines that the user is not proficient using the particular editing tool.

The comparison module 204 generates the proficiency data 210 to include indications of the user's determined proficiency or lack of proficiency using the identified editing tools. In an example in which each identified editing tool corresponds to one of the tutorial steps 124-134, the comparison module 204 generates the proficiency data 210 as having indications that the user is proficient in using editing tools described in tutorial steps 124, 126, and 132 and as having indications that the user is not proficient in using editing tools described in tutorial steps 128, 130, and 134. The modification module 206 receives the proficiency data 210 and the tutorial data 120 and the modification module 206 processes the proficiency data 210 and the tutorial data 120 to generate a modified tutorial.

For example, the modification module 206 can process the proficiency data 210 and the tutorial data 120 to generate the modified tutorial 138 as excluding tutorial steps 124, 126, and 132 based on the indications included in the proficiency data 210 that the user is already proficient in use of editing tools described in tutorial steps 124, 126, and 132. The modification module 206 generates the modified tutorial 138 as including tutorial steps 128, 130, and 134 based on the indications included in the proficiency data 210 that the user is not proficient in using editing tools described in tutorial steps 128, 130, and 134. In the example illustrated in FIG. 1, the modification module 206 generates the modified tutorial 138 having tutorial steps 128, 130, and 134 in a same relative order as the tutorial steps 128, 130, and 134 appear in the tutorial 122.

In other examples, the modification module 206 can generate the modified tutorial 138 having the tutorial steps 128, 130, and 134 in an order based on proficiency scores which may be different from the order of the tutorial steps 128, 130, and 134 in the tutorial 122. For example, if tutorial steps 128, 130, and 134 describe use of first, second, and third editing tools, respectively, then the modification module 206 can generate the modified tutorial 138 as including the tutorial steps 128, 130, and 134 in an order based on proficiency scores for the first, second, and third editing tools.

Consider an example in which a proficiency score for the third editing tool is less than a proficiency score for the first editing tool and less than a proficiency score for the second editing tool. In this example, the proficiency score for the second editing tool is less than the proficiency score for the first editing tool. In one example, the modification module 206 generates the modified tutorial 138 having the tutorial steps 128, 130, and 134 ordered based on the corresponding proficiency scores for the first, second, and third editing tools.

In an example in which the tutorial steps 128, 130, and 134 are rearranged based on ascending order of proficiency scores, the modification module 206 orders tutorial step 134 first, tutorial step 130 second, and tutorial step 128 third. By generating the modified tutorial 138 based on the ascending order of the proficiency scores, the user learns to use the editing tools starting with the editing tools having a lowest proficiency score. This improves user engagement because the user is learning something new.

In an example in which the tutorial steps 128, 130, and 134 are rearranged based on descending order of proficiency scores, the modification module 206 orders tutorial step 128 first, tutorial step 130 second, and tutorial step 134 third. By generating the modified tutorial 138 based on the descending order of the proficiency scores, the user learns to use the editing tools starting with the editing tools having a highest proficiency score. This increases user comfort level because the user is learning something which may already be somewhat familiar to the user.

Consider an example of a tutorial which is organized by chapters and each of the chapters includes multiple tutorial steps which each describe use of a particular editing tool. In this example, the modification module 206 can determine a chapter proficiency score of a particular chapter of the tutorial as an average score of proficiency scores of tutorial steps of the particular chapter. For example, the modification module 206 can order the tutorial steps of the particular chapter based on an ascending or descending order of proficiency scores corresponding to the tutorial steps of the particular chapter. The modification module 206 can also order chapters of the tutorial based on an ascending or descending order of chapter proficiency scores of the chapters. In this way, the modification module 206 can leverage the proficiency scores to remove tutorial steps for learning use of editing tools which the user is already proficient using and also to order tutorial steps for learning use of editing tools which the user is not proficient using.

In one or more implementations, the tutorial module 110 employs Portable Tutorial Format (PTF) to further customize tutorials. Each PTF document represents one tutorial. A PTF document can include multiple chapters and each chapter may include multiple tutorial steps such that there is a one to one mapping between the tutorial steps and editing tools which are described in the tutorial steps. An optional new field is added within each tutorial step and each chapter of the PTF document named “user_attributes.” This new field is generic and can include multiple personalized user attributes in one example. Examples of personalized user attributes can include user language preferences, tutorial duration minimums and/or maximums, volume settings, etc.

The proficiency data 210 is added to the PTF document in the user_attributes field. In this way, the computing device 102 implements the tutorial module 110 to access the proficiency data 210 in the user_attributes field of the PTF document and the tutorial module 110 can use the proficiency data 210 to generate a tutorial as excluding tutorial steps which describe editing tools that the user is already proficient in using. For example, the tutorial module 110 accesses the proficiency data 210 in the user_attributes field of the PTF document to exclude tutorial steps from tutorial chapters of the tutorial. If the user is proficient using editing tools described by all of the tutorial steps of a particular chapter, then the tutorial module can generate the tutorial as excluding the particular chapter.

The tutorial module 110 can also use the proficiency data 210 to generate the tutorial having tutorial steps ordered according to an ascending or descending order of proficiency scores for editing tools described in the tutorial steps. The tutorial module 110 can additionally leverage the proficiency data 210 in the user_attributes field of the PTF document to determine chapter proficiency scores as the average of the proficiency scores corresponding to tutorial steps of the chapters. In this manner, the tutorial module 110 can generate the tutorial having chapters ordered according to an ascending or descending order of the determined chapter proficiency scores.

In an example in which a user_attributes field of a particular PTF document does not include the proficiency data 210 or includes outdated proficiency data, the computing device 102 can implement the tutorial module 110 to include or update the proficiency data 210 in the user_attributes field. By including or updating the proficiency data 210 in the user_attributes field of the PTF document, the proficiency data 210 can be leveraged as previously described. For a typical user, this may amount to approximately a 30% reduction in tutorial duration. Additionally, a modified tutorial generated by leveraging the proficiency data 210 is customized for the user which increases user engagement and retention.

Example Procedures

The following discussion describes techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to FIG. 1 and FIG. 2.

FIG. 3 is a flow diagram depicting a procedure 300 in an example implementation in which a proficiency map is generated that includes proficiency scores for a user's use of editing tools described in corresponding tutorial steps of a tutorial and a modified tutorial is generated having tutorial steps in a modified relative order based on an ascending order of the proficiency scores for the editing tools. A proficiency map is generated for a user based on the user's use of editing tools of an application to edit a digital image (block 302), the editing tools described in corresponding tutorial steps of a tutorial, the proficiency map including proficiency scores for the editing tools that are calculated by comparing edits to the digital image by the user using the editing tools with edits to the digital image by an algorithm of the application using the editing tools, the proficiency scores indicating the user's proficiency using the editing tools. In one example, the computing device implements the tutorial module 110 to generate the proficiency map. The tutorial steps are arranged in a modified relative order based on an ascending order of the proficiency scores of the proficiency map for the editing tools described in the corresponding tutorial steps (block 304). For example, the tutorial module 110 can arrange the tutorial steps in the modified relative order. A modified tutorial having the tutorial steps in the modified relative order is generated (block 306), the modified tutorial generated for display in a user interface. In an example, the tutorial module 110 generates the modified tutorial.

FIG. 4 is an illustration of a representation 400 of a proficiency based tutorial modification. The representation 400 includes a tutorial 402 and a modified tutorial 404. The tutorial 402 begins with an input digital image 406 which will be modified by tutorial steps 408-414 of the tutorial 402. For example, the tutorial steps 408-414 each describe an editing tool and the input digital image 406 is modified by these editing tools as a user progresses through the tutorial steps 408-414 of the tutorial 402.

At tutorial step 408, the input digital image 406 is modified using editing tool A. As shown, editing tool A adds a white oval shape to the input digital image 406 at tutorial step 408. At tutorial step 410, the input digital image 406 is further modified using editing tool B. As illustrated, editing tool B adds a white star shape to the input digital image 406 at tutorial step 410. Thus, the input digital image 406 now depicts the white oval shape added using editing tool A and the white star shape added using editing tool B.

At tutorial step 412, the input digital image 406 is further modified using editing tool C. As shown in FIG. 4, editing tool C adds a white pentagon shape to the input digital image 406 at tutorial step 412. As further shown, the input digital image 406 now depicts the white oval shape added using editing tool A, the white star shape added using editing tool B, and the white pentagon shape added using editing tool C.

At tutorial step 414, the input digital image 406 is further modified using editing tool D. As illustrated, editing tool D adds a white triangle shape to the input digital image 406 at tutorial step 414. The tutorial 402 is now complete and the input digital image 406 now depicts the white oval shape added using editing tool A, the white star shape added using editing tool B, the white pentagon shape added using editing tool C, and the white triangle shape added using editing tool D.

The computing device 102 implements the tutorial module 110 to generate the modified tutorial 404. To do so, the tutorial module 110 processes the user data 118 to generate proficiency scores for editing tools A-D. In one example, the tutorial module 110 may generate proficiency scores according to the following:

${{Proficiency}(T)} = \begin{Bmatrix} {0,} & {n_{T} \leq m_{T}} \\ {{k_{T}/n_{T}},} & {n_{T} > m_{T}} \end{Bmatrix}$ where: T is an editing tool; k_(T) is an approximate number of times tool T was used correctly by the a user; n_(T) is a total number of times tool T was used by the user; and m_(T) is a minimum number of times tool T should be used to become eligible for proficiency calculations, (m_(T)>0).

For example, the tutorial module 110 can count a number of digital images included in the digital content 112 which have been edited and/or created using editing tool T to determine n_(T). The tutorial module 110 can approximate a number of times the editing tool T was used correctly by calculating distances or differences between user applied values to the digital images and application values applied to the digital images. If a particular calculated distance or difference between a particular user applied value and a particular application value applied to a particular digital image is less than a threshold, then the tutorial module 110 determines that the user's use of editing tool T on the particular digital image was approximately correct. Alternatively, if the particular calculated distance is greater than the threshold, then the tutorial module 110 determines that the user's use of editing tool T on the particular digital image was not correct.

In example in which an algorithm for editing tool T is not available, the tutorial module 110 may generate proficiency scores according to the following:

${{Proficiency}(T)} = \frac{1}{1 + e^{{- n_{T}} + m_{T}}}$ where: T is an editing tool; n_(T) is a total number of times tool T was used by the user; and m_(T) is a minimum number of times tool T should be used to become eligible for proficiency calculations, (m_(T)>0). For example, m_(T) may be a use threshold.

In the above examples, each generated proficiency score is compared to a proficiency threshold to determine the user's proficiency using editing tools corresponding to the tutorial steps 408-414 of the tutorial 402. This proficiency threshold may be independent of a particular editing tool or the proficiency threshold may depend on the particular editing tool being evaluated for proficiency. For example, a difficult editing tool may have a greater threshold for proficiency than a simple editing tool.

Consider an example in which the tutorial module 110 compares differences between user modifications applied to a particular digital image using editing tools A-D and application modifications applied to the particular digital image by algorithm of an application for editing digital images using editing tools A-D. In this example, the tutorial module 110 determines a user modification applied to the particular digital image by a user using editing tool A. The tutorial module 110 also determines an application modification applied to the particular digital image by the application for editing digital images using editing tool A. Continuing this example, the tutorial module 110 determines a difference between the user modification and the application modification. For example, the tutorial model 110 may calculate a proficiency score for the user's use of editing tool A based on this difference. In one example, the tutorial module 110 can compare the difference to a difference threshold as part of calculating the proficiency score such as to determine that the difference between the user modification and the application modification is less than the difference threshold. For example, the tutorial module 110 may generate proficiency scores for editing tools B-D in this manner as well.

In one example, the computing device 102 implements the tutorial module 110 to update a proficiency map to include proficiency scores for editing tools A-D. For example, the proficiency map maps a user's proficiency scores for editing tools to an application for editing digital images. As the tutorial module 110 computes proficiency scores for editing tools, the tutorial module 110 may update the proficiency map to include proficiency scores for new editing tools or updated proficiency scores for existing editing tools.

After generating the proficiency scores for editing tools A-D, the tutorial module 110 compares the proficiency scores to a proficiency threshold. In the illustrated example, the proficiency score for editing tool C is greater than the proficiency threshold and the proficiency scores for editing tools A, B, and D are below the proficiency threshold. Thus, the tutorial module 110 determines that the user is proficient in using editing tool C and that the user is not proficient in using editing tools A, B, and D. The tutorial module 110 generates the modified tutorial 404 as excluding a tutorial step corresponding to editing tool C.

The tutorial module 110 also generates a modified input digital image 416 which is the input digital image 406 modified using editing tool C. For example, the modified input digital image 416 is a pre-modified digital image depicting modifications applied to the input digital image 406 using editing tool C based on the proficiency score for editing tool C being greater than the proficiency threshold. As shown, the modified input digital image 416 depicts the white pentagon shape corresponding to editing tool C. The modified tutorial 404 is illustrated to include tutorial steps 418-422 in which the modified input digital image 416 will be further modified by editing tools described in the tutorial steps 418-422.

At tutorial step 418, the modified input digital image 416 is modified using editing tool A. As shown, editing tool A adds the white oval shape to the modified input digital image 416 at tutorial step 418. The modified input digital image 416 now depicts the white pentagon shape added using editing tool C to generate the modified input digital image 416 and the white oval shape added using editing tool A.

At tutorial step 420, the modified input digital image 416 is further modified using editing tool B. As illustrated, editing tool B adds the white star shape to the modified input digital image 416 at tutorial step 420. Thus, the modified input digital image 416 now depicts the white pentagon shape added using editing tool C, the white oval shape added using editing tool A, and the white star shape added using editing tool B.

At tutorial step 422, the modified input digital image 416 is further modified using editing tool D. As illustrated, editing tool D adds the white triangle shape to the modified input digital image 416 at tutorial step 422. The modified tutorial 404 is now complete and the modified input digital image 416 depicts the white pentagon shape added using editing tool C, the white oval shape added using editing tool A, the white star shape added using editing tool B, and the white triangle shape added using editing tool D. As shown, the modified input digital image 416 at tutorial step 422 is the same as the input digital image 406 at tutorial step 414. This is because the editing tools A-D are order independent in this example.

In some examples, the tutorial module 110 may leverage the proficiency scores for editing tools A, B, and D to rearrange an order of tutorial steps 418-422. Consider an example in which the proficiency score for editing tool B is lower than the proficiency scores for editing tools A and D. In this example, the proficiency score for editing tool A is higher than the proficiency score for editing tool D. For example, the computing device 102 can implement the tutorial module 110 to order the tutorial steps 418-422 in ascending order of the proficiency scores of the editing tools described in the tutorial steps 418-422. In this example, the tutorial module 110 orders tutorial step 420 first, tutorial step 422 second, and tutorial step 418 third. In an example in which the tutorial module 110 orders the tutorial steps 418-422 in descending order of the proficiency scores of the editing tools described in the tutorial steps 418-422, the tutorial module 110 orders tutorial step 418 first, tutorial step 422 second, and tutorial step 420 third.

Consider another example in which the tutorial module 110 may leverage the proficiency scores for editing tools A, B, and D to rearrange chapters of a tutorial. For example, the modified tutorial 404 may be a chapter of another tutorial and the tutorial module 110 determines a chapter proficiency score of the chapter as an average of the proficiency scores for editing tools A, B, and D. In this way, the tutorial module 110 can leverage the chapter proficiency score of the chapter and an additional chapter proficiency score of an additional chapter to order the chapter and the additional chapter based on the chapter proficiency score and the additional chapter proficiency score. This chapter ordering can be in ascending or descending order of chapter proficiency scores.

FIG. 5 is an illustration of a representation 500 of an additional proficiency based tutorial modification. The representation 500 includes the tutorial 402 and a modified tutorial 502. In this example, the tutorial 402 begins with an input digital image 406 which will be modified by editing tools A-D at corresponding tutorial steps 408-414 of the tutorial 402. To generate the modified tutorial 502 the computing device 102 implements the tutorial module 110 which processes the user data 118 to generate proficiency scores for editing tools A-D. For example, the tutorial module 110 may update the proficiency map to include proficiency scores for editing tools A-D.

After generating the proficiency scores for editing tools A-D, the tutorial module 110 compares the proficiency scores to a proficiency threshold. In this example, the proficiency scores for editing tools B and D are greater than the proficiency threshold and the proficiency scores for editing tools A and C are below the proficiency threshold. Thus, the tutorial module 110 determines that the user is proficient in using editing tools B and D and that the user is not proficient in using editing tools A and C. The tutorial module 110 generates the modified tutorial 502 as excluding tutorial steps corresponding to editing tools B and D.

The tutorial module 110 also generates a modified input digital image 504 which is the input digital image 406 modified using editing tools B and D. As shown, the modified input digital image 504 depicts the white star shape corresponding to editing tool B. The modified input digital image 504 also depicts the white triangle shape corresponding to editing tool D. However, the modified input digital image 504 does not depict the white oval shape or the white pentagon shape corresponding to editing tools A and C, respectively. This is because the user is not proficient in using editing tools A and C.

The modified tutorial 404 is illustrated to include tutorial steps 506, 508 in which the modified input digital image 504 will be further modified by editing tools described in the tutorial steps 506, 508. At tutorial step 506, the modified input digital image 504 is modified using editing tool A. As illustrated, editing tool A adds the white oval shape to the modified input digital image 504 at tutorial step 506. The modified input digital image 504 now depicts the white star shape added using editing tool B and the white triangle shape added using editing tool D to generate the modified input digital image 504 as well as the white oval shape added using editing tool A.

At tutorial step 508, the modified input digital image 504 is further modified using editing tool C. As shown, editing tool C adds the white pentagon shape to the modified input digital image 504 at tutorial step 508. The modified tutorial 502 is now complete and the modified input digital image 504 depicts the white star shape added using editing tool B, the white triangle shape added using editing tool D, the white oval shape added using editing tool A, and the white pentagon shape added using editing tool C. As further shown, the modified input digital image 504 at tutorial step 508 is the same as the input digital image 406 at tutorial step 414 because the editing tools A-D are order independent in this example.

FIG. 6 is a flow diagram depicting a procedure 600 in an example implementation in which a tutorial step of a tutorial is removed based on a proficiency score indicating a user's proficiency in using an editing tool corresponding to the tutorial step. A user modification of a digital image is received (block 602), the user modification corresponding to a user's use of an editing tool of editing tools of an application for editing digital images to edit the digital image, the editing tools corresponding to tutorial steps of a tutorial. The computing device 102 can implement the tutorial module 110 to receive the user modification of the digital image. A difference between the user modification and an application modification of the digital image is determined (block 604), the application modification corresponding to use of an algorithm of the application to edit the digital image. For example, the tutorial module 110 determines the difference between the user modification and the application modification.

A proficiency score for the editing tool is computed based on the difference between the user modification and the application modification (block 606), the proficiency score indicating the user's proficiency in using the editing tool. In one example, the tutorial module 110 computes the proficiency score based on the difference between the user modification and the application modification. The proficiency score for the editing tool is compared to a proficiency threshold (block 608). The computing device 102 implements the tutorial module 110 to compare the proficiency score for the editing tool to the proficiency threshold in one example. A tutorial step of the tutorial steps of the tutorial is removed in response to the proficiency score for the editing tool being greater than the proficiency threshold (block 610), the tutorial step corresponding to the editing tool. For example, the tutorial module 110 removes the tutorial step of the tutorial steps of the tutorial in response to the proficiency score for the editing tool being greater than the proficiency threshold.

The cloud 714 includes and/or is representative of a platform 716 for resources 718. The platform 716 abstracts underlying functionality of hardware (e.g., servers) and software resources of the cloud 714. The resources 718 may include applications and/or data that can be utilized while computer processing is executed on servers that are remote from the computing device 702. Resources 718 can also include services provided over the Internet and/or through a subscriber network, such as a cellular or Wi-Fi network.

The platform 716 may abstract resources 718 and functions to connect the computing device 702 with other computing devices. The platform may also serve to abstract scaling of resources to provide a corresponding level of scale to encountered demand for the resources that are implemented via the platform. Accordingly, in an interconnected device embodiment, implementation of functionality described herein may be distributed throughout the system 700. For example, the functionality may be implemented in part on the computing device 702 as well as via the platform 716 that abstracts the functionality of the cloud 714.
